Dr. Jahan’s Background

Dr. Jahan has lived in France, the United States, and Venezuela. His inspiration to pursue oncology was realized at the age of 8 when he watched his mother recover from a serious illness.

“As an eight-year-old, I said, ‘I want to do what those doctors do: I want to give another kid his mom back.'”

- Dr. Thierry Jahan

The motivation to help others followed Dr. Jahan into adulthood. He began his medical education at Université de Paris V-René Descartes before transferring to the Vagelos College of Physicians and Surgeons at Columbia University in New York.

He earned his medical degree from George Washington University School of Medicine. From there, Dr. Jahan moved to California to complete an internal medicine residency at UCLA Department of Medicine Cedars-Sinai Medical Center.

Dr. Jahan’s Medical Specializations

Dr. Jahan is a board-certified medical oncologist who specializes in thoracic cancers, including pleural mesothelioma.

“[At UCSF] we offer solutions and possibilities. I tell patients, ‘This is what the average patient can expect, but I’m shooting for the good side of the bell curve.’ I empower them to make decisions about how they want to face their disease.”

- Dr. Thierry Jahan

When working with mesothelioma patients, Dr. Jahan considered each case individually to suggest an optimal treatment plan that is unique to each person. He was well known for treating pleural mesothelioma in a multimodal approach that combined mesothelioma surgery with chemotherapy, radiation, and any other possible options.

Some of these treatment suggestions arise from the groundbreaking clinical trials and medical research undertaken by the medical oncology group previously led by Dr. Jahan. He also investigated different combinations of mesothelioma treatments to determine which combinations worked best in different scenarios.
